TL* THE CONTACT OWNS A 2015 GMC YUKON DENALI XL. THE CONTACT STATED THAT THE VEHICLE EMITTED AN ABNORMAL FUEL ODOR. UPON INSPECTION, THE CONTACT OBSERVED A PUDDLE OF FUEL ON THE GROUND. THE CONTACT ALSO NOTICED THAT THE FUEL TANK AND FUEL LINE DID NOT HAVE ENOUGH SPACE IN BETWEEN THEM, WHICH CAUSED A HOLE TO DEVELOP IN THE FUEL LINE. THE DEALER AND MANUFACTURER WERE NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 68,000. **TR CONSUMER STATED FUEL WAS LEAKING FROM PRESSURE LINE TO ENGINE ABOVE FUEL TANK. WHEN TANK WAS REMOVED THE FUEL LINE HAD RUBBED A HOLE IN ITSELF FROM THE WHERE IT CLIPS INTO THE TANK. THE LINE HAD PUSHED OUT ALMOST 2 GALLON OF FUEL IN LESS THEN 10 MINUTES OF IDLING TIME IN MY GARAGE. UPDATE 11/1/18*JB

WHEN USING STEERING TO TURN AROUND, TURN INTO A PARKING SPACE OR BACK IN, 'PARKING ASSIST OFF' SHOW UP ON THE INSTRUMENT PANEL, THEN THE STEERING WHEELS LOCKS AND THE CAR TURNS OFF WHILE STILL ENGAGED IN DRIVE. SOMETIMES 'BRAKE ASSIST' COMES ON FIRST. EXTREMELY DANGEROUS. WHEN THIS HAPPENS, UNABLE TO TURN STEERING WHEEL. CAR SHUTS DOWN AND DOORS LOCK. I HAVE TO PUT IT IN PARK AND RESTART THE CAR. SOMETIMES IT DOES IT MORE THAN ONCE AFTER RESTARTING THE CAR. I HAVE TAKEN IT TO A GMC DEALER FOR EVALUATION AND REPAIR. HAS HAPPENED AT LEAST 6 DIFFERENT TIMES. WHEN DRIVING, I AM ALWAYS AFRAID TO MAKE SHARP TURNS. HOWEVER, IT HAS ONLY HAPPENED AT SLOW SPEEDS WHEN TRYING TO TURN IN TO A DRIVEWAY OR TURN AROUND SUCH AS IN A PARKING LOT. *DT CONSUMER STATED AFTER TAKING MY CAR TO GMC DEALER AND BEING TOLD MY VEHICLE NEEDED A SORTWARE UPDATE, MY CAR WENT A FEW WEEKS WITHOUT AN EPISODE UNTIL THIS EVENING AT 7:52PM EASTERN TIME, WHILE BACKING IN TO MY DRIVEWAY. THE STEERING WHEEL KICKED IN PLACE AND THE VEHICLE TURNED OFF AND DOORS LOCKED, LEAVING ME OUT IN THE STREET, UNABLE TO CONTROL MY CAR FOR SECONDS. UPDATED 10/18/18*JB UPDATED 10/26/18*JB

REAR LEFT TAIL LIGHT AND BRAKE LIGHT WORK INTERMITTENTLY. YET STARTED HAPPENING AND CAR WILL NOT PASS INSPECTION IN THE STATE OF VA. WHEN NOTICED THE VEHICLE WAS PARKED, BUT HAVE ALSO SEEN WHILE DRIVING.

NHTSA ODI 11124662

THE PASSENGER TAIL LIGHT IS WORKING INTERMITTENTLY. THE DEALER SAID THAT THE ONLY FIX IS TO BUY A NEW BRAKE LIGHT UNIT @ $650. AFTER SEARCHING ON LINE, OTHER OPTIONS ARE TO SEND BRAKE LIGHT UNIT OFF FOR REPAIR, OR PURCHASE AFTER MARKET BRAKE LIGHT UNIT. AS MANY PEOPLE THAT ARE HAVING THIS SAME ISSUE, IT SURE SEEMS LIKE GMC WOULD CORRECT THIS FAULTY BRAKE LIGHT.

FRONT RIGHT LED DAYLIGHT LIGHT IS OUT. CAR IS OUT OF WARRANTY, AND PART IS APPROXIMATELY $750 TO REPLACE, VICE JUST A BULB SWAP. CAR HAS ABOUT 90K MILES ON IT. LED DAYLIGHT IS NOT ABLE TO BE REPAIRED. I BELIEVE IT'S REFERRED TO AS DRL. DEALERSHIP WILL NOT REPLACE IN WARRANTY, BECAUSE CAR IS OUT OF WARRANTY - AND REPLACEMENT FOR A LIGHT IS OVER $700....ABSOLUTELY UNACCEPTABLE AND UNSUSTAINABLE. ESPECIALLY SINCE THIS MODEL IS A 2015 MODEL. OVER THE LIFE OF THIS VEHICLE, HOW MANY TIMES AM I EXPECTED TO REPLACE A $750 LED HOUSING?

NHTSA ODI 11123998

RIGHT SIDE LED BRAKE LIGHTS ARE NOT WORKING. IT IS A KNOWN PROBLEM WITH THE ELECTRICAL TRACES IN SIDE THE SEALED LIGHT. REPLACEMENT IS $600!

NHTSA ODI 11123993

THE REAR LED BRAKE TAIL LIGHT STOPPED WORKING DUE TO A CRACK IN THE CONDUCTIVE PLATE INSIDE THE ASSEMBLY.

NHTSA ODI 11123801

A/C IN AUTOMOBILE STOPPED WORKING. THERE ARE ALLEGEDLY TWO DEFECTIVE PARTS IN THIS VEHICLE. THE DISCHARGE LINE AND THE CONDENSER. BOTH ARE TOO WEAK TO HANDLE THE PRESSURE FROM THE COOLANT

NHTSA ODI 11123393

THE REAR LED TAILIGHT GOES IN AND OUT, WHILE DRIVING THE CAR. THE DEALER WILL NOT FIX THE PROBLEM UNLESS THE LIGHT IS NOT WORKING, BUT BECAUSE IT IS INTERMITTENT, WE CANNOT GET IT TO FAIL AT THE DEALERSHIP. WE HAVE HAD THIS PROBLEM FOR 2 YEARS AND IT IS A SAFETY ISSUE AS THE TAIL LIGHT WILL NOT WORK.

NHTSA ODI 11123163

PASSENGER SIDE REAR BRAKE LIGHT AND TAIL LIGHT STOPPED WORKING. THIS CANNOT BE FIXED WITH A SIMPLE BULB. THIS IS AN INTEGRATED LED REQUIRING THE ENTIRE TAIL LIGHT ASSEMBLY TO BE REPLACED AT THE OWNERS EXPENSE. DEALER ESTIMATE WAS $800 AFTER INSTALLING.

MULTIPLE COMPLAINTS HAVE BEEN FILLED WITH GMC ABOUT THEIR POOR BRAKE DESIGN ON THEIR 2015- 2019 YUKONS THE CIRCUIT BREAKS AND THE TAIL LIGHT ASSEMBLY QUITS WORKING. YUKON SAYS THEY HAVE NOT HEARD OF SUCH COMPLAINTS. AND WILL NOT RECALL THEIR POOR ASSEMBLY DESIGN.

NHTSA ODI 11123144

DRIVERS SIDE TAILLIGHT STOPPED WORKING. SIGNAL STILL OPERATING.

NHTSA ODI 11122286

TAIL LIGHT NO LONGER WORKING. SAFETY HAZARD. IT STARTED FLASHING INTERMITTENTLY AND SMELLING FUNNY NOW IT WON'T WORK AT ALL. THIS WILL CAUSE AN ACCIDENT AND OF COURSE IT'S NOT UNDER WARRANTY AS I'M AT 60K BUT GMC WILL DO NOTHING FOR IT EVEN THOUGH THIS IS A WIDELY KNOWN ISSUE. I CONTACTED THEM AND THEY WILL DO NOTHING!

NHTSA ODI 11121900

BRAKE LIGHTS HAVE FAILED. I APPEARS TO BE DUE TO A FAULTY SOLIDER ON THE LED ASSEMBLY. BOTH BRAKE LIGHTS HAVE NOW FAILED. THE FAULT IS CONSTANT AND HAS NO RELATIONSHIP TO STATUS OF THE OPERATION OF THE VEHICLE OR ROAD CONDITIONS. CONSUMER CAN NOT REPAIR THE FAULT DUE TO THE DESIGN OF THE TAIL LIGHT ASSEMBLY. THE VEHICLE OWNER AND OTHER DRIVERS ARE BEING ENDANGERED BY THIS ISSUE THAT IS OBVIOUSLY A QUALITY ISSUE WITH THE PRODUCT.

NHTSA ODI 11121588

BOTH BRAKE LIGHTS FAILED WITHIN DAYS OF EACH OTHER. THE FAILURE WAS THE SAME AS INDICATED HERE: HTTPS://WWW.CARGURUS.COM/CARS/DISCUSSION-T53845_DS768963 . I HAVE PICTURES OF THE FAILED PIECE.

SUNROOF: WHILE TRAVELING ON THE ROAD AT 55MPH, MY SUNROOF, WHICH WAS CLOSED, RANDOMLY EXPLODED. YOU CAN SEE THE GLASS ACTUALLY PUSHED UP AND OUT WHEN IT BLEW. WE HAD GLASS EVERYWHERE IN THE VEHICLE. THERE WERE NO OTHER VEHICLES AROUND ME AND THERE WAS NOTHING THAT CAME THROUGH THE WINDOW. IT WAS A NICE SUNNY DAY, NO RAIN OR OTHER REASON FOR THIS TO HAVE HAPPENED. I STOPPED RIGHT AWAY AND TOOK PHOTOS OF THE DAMAGE. I CALLED MY INSURANCE COMPANY RIGHT AWAY AND AM WAITING FOR THE SUNROOF TO BE REPLACED.

AFTER ABOUT 1 YEAR OF OWNING THIS VERY EXPENSIVE VEHICLE (BOUGHT IT WHEN IT WAS ABOUT 2 YEARS OLD, IE. 2017) USED FROM A GMC DEALER - THE DRIVERS SIDE TAIL LIGHT STARTED WORKING ONLY INTERMITTENTLY AND THEN STOP WORKING ALL TOGETHER. I HAD THE DEALER ESTIMATE THE REPLACEMENT COST AND THEY TOLD ME IT WOULD BE $1,500 TO REPLACE BOTH TAIL LIGHTS (SAID I NEEDED TO REPLACE THE ENTIRE ASSEMBLY BECAUSE THEY WERE LED????). THIS IS ABSURD ON SO MANY LEVELS...THESE ARE ONE OF THE MOST EXPENSIVE VEHICLES ON THE MARKET AND WITHIN ONLY A FEW YEARS THE TAIL LIGHTS NEED TO REPLACED...AT AN OUTRAGEOUS COST. MY LAST YUKON (2007) DIDN'T HAVE A TAIL LIGHT GO OUT FOR MANY YEARS...AND I BOUGHT A REPLACEMENT BULB FOR $3 AND DID IT MYSELF. AFTER DOING SOME RESEARCH, IT APPEARS TO BE A "COMMON" ISSUE FOR THESE GMC VEHICLES...AND THE FACT THAT GMC IS WELL AWARE OF THIS IS DOING NOTHING ABOUT A KNOWN AND PERSISTENT ISSUE IS FRUSTRATING.

NHTSA ODI 11120090

TAILIGHT BRAKE LIGHT NOT WORKING, NO REPLACEMENT BULB AVAILABLE, GM SAYS MUST BE ENTIRE UNIT AND HOUSING FOR $701. THIS IS RIDICULOUS AND ONEROUS. THIS IS CLEARLY A DEFECTIVE DESIGN AND DEFECTIVE PART. SHOULD BE REPLACED OR REPAIRED FOR FREE.

RIGHT TAIL LIGHT BEGAN TO NOT WORK LAST FALL. I WENT TO HAVE IT CHECKED THEN IT WAS WORKING FINE. WENT IN FOR ABOUT A MONTH. SOMETIMES IT WORKED THEN IT WASN'T. ALMOST LIKE IT HAD A SHORT. EVENTUALLY HAD TO REPLACE WHOLE SYSTEM NOT JUST A BULB. NOW ALMOST ONE YEAR LATER THE SAME THING IS HAPPENING ON THE LEFT SIDE. THIS IS A $1,000 ITEM. I HAVE OWNED CARS FOR TEN YEARS AND NEVER HAD TO REPLACE A LIGHT. READ ONLINE THAT THERE ARE MANY ISSUES WITH THESE TAIL LIGHTS.

NHTSA ODI 11119832

BAD LED BRAKE LIGHTS: WE PURCHASED OUR GMC YUKON XL 2015 IN MAY 2016. SINCE THEN WE HAVE HAD TO REPLACE BOTH BRAKE LIGHTS(1 AFTER A YEAR-MARCH 2017 AND THE 2ND AFTER 2 YEARS-AUG 2018) AND HAVE HAD THE VEHICLE ONLY 2 YEARS. THEY ARE LED LIGHTS SO NOT A CHEAP REPAIR. QUOTED COST $750-$2000. SO FAR, OUR WARRANTY HAS COVERED THE REPAIRS BUT ONCE WARRANTY IS OFF, IT WILL COST TOO MUCH TO REPAIR AND IS NOT SAFE TO DRIVE WITHOUT REPAIRING! WE HAVE HAD MANY VEHICLES OVER THE YEARS AND HAVE ONLY REPLACED BRAKE LIGHTS 2-3 TIMES AND FOR LESS THAN $25 EACH TIME. THIS APPEARS TO BE A BAD DESIGN OR FAULTY PARTS BY GMC. ONE OF THE FAILURES WAS DUE TO INTERNAL SHORT IN THE LED MODULE. WE WOULD LIKE GMC TO RESOLVE THE FAULTY PARTS AND RECALL THE PART AND FULLY REPLACE OUR BRAKE LIGHTS WITH RELIABLE LIGHTS VS LIGHTS THAT ONLY LAST A YEAR. THANK YOU!
